Abstract
A rotational machine such as a turbocompressor has a fluid recovery system for recovering leaked working fluid such as gaseous helium in a helium circuit which has leaked past a shaft seal, a purifier being provided for removing contaminants from the working fluid, and turbocompressor may have one fluid such as helium or hydrogen working through one turbo component such as a turbine thereof and a second working fluid such as air or helium working through a second turbo component such as a compressor thereof, the rotational machine being installable in an engine of a flying machine.
Claims31
A rotational machine having a working component for communicating a working fluid from an inlet to an outlet thereof, comprising:
- a rotor;
- a connector for mechanical communication from the rotor;
- and
- a working fluid recovery system for the recovery of working fluid in the region of the connector.
A machine, comprising:
- a working fluid circuit, the working fluid circuit comprising a purifier for removing contaminants from the working fluid.
A machine, comprising:
- a helium fluid rotor;
- a non-helium fluid rotor;
- a shaft, wherein the helium fluid rotor is drivingly connected to the non-helium fluid rotor by the shaft;
- a shaft seal between the helium fluid rotor and the non-helium fluid rotor, wherein the machine is adapted to operate with a pressure gradient along the shaft with a higher pressure on a helium fluid side of the shaft seal than on a non-helium fluid side of the shaft seal.
